Yes, I've seen cards lock up under heavy traffic too. Sometimes it
was a driver problem, but with this particular card I just removed it
from the system altogether and replaced it with something more
reliable. With an ISA-based 486, this meant another 10baseT card,
but I found a 3c509b and a DE220 which are currently working very
reliably.
